18515-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18515-05-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,5,1 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 18515-05:
(7*1)+(6*8)+(5*5)+(4*1)+(3*5)+(2*0)+(1*5)=104
104 % 10 = 4
So 18515-05-4 is a valid CAS Registry Number.
